Update time : 2021-12-31 15:10:28

Many families choose to install a water purifier. Different types of water purifiers have different effects. A water purifier that is unplugged and has no waste water sounds environmentally friendly and energy-saving. Compared with the water purifier that needs to be plugged in , How to choose?

Some people think that an unplugged water purifier is better!
There is a kind of water purifier called ultrafiltration water purifier, which is plug-in-free.
Ultrafiltration is a screening principle of membrane separation technology. The driving force is the pressure difference on both sides of the membrane.

Under a certain pressure, when tap water flows through the membrane surface, the micropores on the ultrafiltration membrane surface only allow water and small molecules to pass through, while the substances whose volume is larger than the micropores on the membrane surface are intercepted, so as to achieve the purpose of purifying water.

The pore size is about 0.01μm, allowing only water molecules, beneficial minerals and trace elements in water to pass through.
Under normal circumstances, the volume of bacteria is greater than 0.02μm, so the ultrafiltration membrane can be used to trap bacteria and colloids, rust, suspended solids, sediments, etc. that are much larger than bacteria.

The unplugged water purifier produced by this technology does not need to discharge waste water, and is environmentally friendly and does not waste tap water.

Such a water purifier is very cost-effective to use in the kitchen, because the kitchen water consumption is large, and the tap water purified by the ultrafiltration water purifier is just suitable for the needs of kitchen water. Therefore, the ultrafiltration water purifier has an advantage in the kitchen water purifier.

This kind of ultrafiltration water purifier does not need to be plugged in, which brings convenience to some users who do not have a reserved power interface. It can be installed in the kitchen to wash vegetables and cook.
The ultrafiltration water purifier does not require electricity, so it is much easier to install the line, and it will not produce any noise when it is not plugged in, just like nothing is installed!

However, some advertisements are exaggerated and misleading:

First, the tap water purified by the ultrafiltration water purifier can also be drunk directly.

As mentioned earlier, the filtration accuracy of the ultrafiltration water purifier is only 0.01 micron, which cannot filter bacteria, viruses, heavy metals, etc. in the water. Tap water cannot be filtered clean and cannot achieve the effect of direct drinking, so this is a wrong statement!

Second, the ultrafiltration water purifier has no waste water and saves a lot of tap water.

This is the advantage of the ultrafiltration water purifier. Compared with the reverse osmosis water purifier, it has no waste water and can save a lot of tap water.
Reverse osmosis water purifiers have high filtration accuracy and must produce a certain amount of waste water. Some water purifiers have a lot of waste water, so they bring waste from incoming water, but these waste water is not dirty and can be recycled and there is no waste. Up.

Third, the water purified by the ultrafiltration water purifier contains minerals, which are beneficial to the body?

The reason why the ultrafiltration water purifier can retain beneficial minerals is not that it automatically retains and the water purification effect is limited. It cannot intercept these beneficial substances, so it can retain the beneficial minerals. However, if the water pollution is serious, heavy metals, bacteria and viruses in the water In many cases, ultrafiltration water purifiers cannot filter and cannot intercept harmful substances. Therefore, ultrafiltration water purifiers are not suitable for serious water pollution.

Tips for drinking water era:
If you don’t know the types of water purifiers, you may not know which ones do not need to be plugged in or which do not have waste water. When you see different types of water purifiers in the market, you don’t know which one to choose. ?

Then a water purifier that is unplugged and has no waste water is a good choice, especially when used in the kitchen, which can save a lot of water and electricity bills.
The ultrafiltration water purifier can retain some beneficial elements in the water during the working process.
However, ultrafiltration water purifiers also have their own shortcomings. For example, water purification cannot achieve the effect of direct drinking, that is, raw tap water.
Therefore, it is only suitable for the needs of kitchen water. In terms of direct drinking water, it is not as good as a reverse osmosis water purifier.

The reverse osmosis water purifier has a higher water purification effect, which is suitable for drinking water needs and meets direct drinking. Therefore, when buying a water purifier, if it is only for kitchen water, then an ultrafiltration water purifier is sufficient. It is cost-effective and does not need to be plugged in. Electricity, no waste water. The use cost will be much lower.

Do you know the seven major phenomena of reverse osmosis membranes?

Aug .22.2024

Reverse osmosis is a water treatment process that developed rapidly in the 1960s. At present, it has been used in urban water, boiler feed water, power plant boiler feed water, industrial wastewater, seawater desalination, and solute separation in various solutions. The working principle of the reverse osmosis membrane is to use pressure as a driving force to separate the solvent from the solution. It has good applications in food, electronics, medicine, printing and dyeing and other industries. In the long-term use process, some problems are inevitable. How are some of the "phenomena" that appear in the application of reverse osmosis membranes formed?
